thanks for the great feedback! i also noticed the issues but couldn't fix them in time sadly, the things you mentioned are definitely on the bucket list though.
thanks, i didn't even know about offscreen and collisionIgnore! i saw the optimization section in the kaplay docs but forgot to look at it apparently, so this is super helpful
i loved the art and area design, and i thought the mutated plants looked really cool. my only suggestion is to reduce the jump a little, since the player gets stuck in the ceiling and can sometimes access the outside of the level
